Description

  The present invention relates to an alternative system and an alternative method for a measuring instrument used for purchasing or selling electric power generated by solar power generation or the like.

  In-house power generation such as solar power generation and wind power generation is widely used. For example, DC power generated by solar power generation is converted into AC power by an inverter, and this AC power covers the power consumed in the daytime. When the amount of power generated by solar power generation is greater than the self-consumption power and surplus power is generated, this surplus power can be sold to an electric power company. For this purpose, a service line connected to the distribution network of the electric power company is used, and a measuring instrument for selling electricity for photovoltaic power generation is connected to this service line. A power meter measures the amount of power that flows backward to the distribution network. Since the amount of power sold is calculated based on the number of instructions from the meter for power sale, the solar power generation facility installer (hereinafter referred to as “installer”) has a fee according to the calculated amount of power. Paid.

By the way, the measuring instrument for electric power sale has passed the test according to the regulations (Article 16 of the Measurement Law, etc.), and it cannot be used for electric power sales unless it is within the valid period. For this purpose, the installer must regularly receive a meter for measuring electricity sold. For example, in the case of car inspection of automobiles, there are various systems for performing vehicle inspection smoothly (see, for example, Patent Document 1), but no system has yet been established for the verification of power measuring instruments. Therefore, the electric power company notifies the installer several months before the expiration of the verification period of the power sale measuring instrument, and prompts the verification of the power sale measuring instrument.
JP 2002-123596 A

  However, many of the installers who have received notification of the expiration of the verification period have no knowledge of the verification, and even if they recognize the necessity of the verification, they often do not know the handling method. For this reason, even though the expiration date for certification is approaching, verification of power meter is not performed smoothly, and reverse power flow using power meter that has not been re-certified occurs. Yes.

  Further, since the measuring instrument for power sale is removed from the service line during the verification, surplus power does not flow to the power network via the service line. In other words, since no reverse power flow occurs, the installer cannot sell surplus power during the verification of the power meter.

  An object of the present invention is to provide an alternative measuring instrument system and an alternative measuring instrument method that can solve the above-mentioned problems and enable a smooth verification of an electric power selling measuring instrument.

In order to solve the above-mentioned problem, the invention of claim 1 manages a plurality of power sale measuring instruments that measure the amount of power sold, and for each identification number for identifying each power sale measuring instrument, the certification expiry date and model Validity expiration date for each meter for power sale that stores the number of instructions for the previous month and the number of instructions for this month, and the identification number for identifying each alternative meter A first server for storing alternative measuring instrument data storing the number of attachment instructions and the number of removal instructions for calculating the amount of electricity sold while using the model, manufacturer name and alternative measuring instrument ; A second server that manages the verification of the electric power sale measuring instrument, and a plurality of verified electric power supply alternative measuring instruments prepared as alternatives to the electric power sale measuring instrument.

The third server transmits a replacement work completion report to the second server when the replacement work of the power sale measuring instrument is completed. When the second server receives the replacement work completion report, the second server transmits the alternative measuring instrument information to the first server. The first server updates the power sale meter data and the substitute meter data, copies the power sale meter data to the alternative storage area, and resets the power sale meter data. When the third server finishes taking over the alternative measuring instrument, the third server transmits an exchange end report to the second server. When the second server receives the exchange end report, the second server transmits measuring instrument information to the first server. The first server updates the power sale meter data and the substitute meter data. The first server stores the amount of power sold until the power sale meter is removed based on the power sale meter data in the storage area at the time of substitution, the substitution meter data, and the power sale meter data. Then, the amount of electricity sold this month is calculated from the amount of electricity sold measured by the alternative meter for electricity sale and the amount of electricity sold by the certified electricity meter for sale.

According to a second aspect of the present invention, in the alternative system of the measuring instrument according to the first aspect, the second server includes the power selling meter and the power selling meter data of the application received from the owner. To determine whether or not the data such as the model, manufacturer name, serial number, etc., of the meter for power sale match .

According to the invention of claim 1 , when the second server orders the third server for replacement work of the power sale measuring instrument and the power sale alternative measuring instrument, and the third server receives an order for replacement work, An alternative meter for selling electric power that can be exchanged for an electric meter is selected from the alternative meters for selling electric power managed by the third server. As a result, when the third server is installed at a replacement company, for example, the worker of the replacement company is slow to remove the power meter to be verified and install an alternative power meter. Can be done smoothly. Moreover, even if the installer does not have knowledge of the certification or the installer is not familiar with the certification, the meter for power selling can be received smoothly and can be sold even while the meter for power selling is certified. Electricity can be sold with an alternative electric measuring instrument. Moreover, since the alternative measuring instrument for electric power sale has been verified, it can be prevented from violating the regulations even if a reverse power flow occurs.

In addition, when installing an alternative measuring instrument for power sale, link the indicated number of the measuring instrument for power selling that has been used up to now with the indicated number of the alternative measuring instrument for power sale installed, When removing the alternative meter for power sale, the number of instructions for the alternative meter for power sale that was used is linked to the number of instructions for the certified meter for power sale. Even if it is removed during the test, the owner can obtain an accurate amount of electric power sold without interruption.

According to the invention of claim 2 , the second server determines whether or not the power sale measuring instrument of the application received from the owner matches the power sale measuring instrument data to be verified. Since it is determined whether or not the power sale measuring instrument for which the applicant has applied for verification is a power sale measuring instrument to be verified, it is possible to prevent misidentification of the power selling measuring instrument to be verified.

  Next, an alternative method of a measuring instrument using the alternative system of the measuring instrument according to this embodiment will be described. The charge server 3 of the electric power company checks the power sale measuring instrument for which the verification period has expired based on the “validation expiration date” of the power sale measuring instrument data 32. For example, the fee server 3 sets two months before the “validation expiration date” as a predetermined period, and when the current date enters this predetermined period, as illustrated in FIG. The name and the e-mail address of the installer of the photovoltaic power generation system 11 are checked from the “identification number” of “A0123” corresponding to “0510” of the “validation date”, and as shown in FIG. A verification period expiration notice S1 is sent to the installer terminal 1 to notify that the verification period of the power sale measuring instrument has expired, and the “verification” of the power sale measuring instrument data 32 is set to “incomplete”. An application form 200 shown in FIG. 9 is attached to the certification period expiration notice S1 sent by the fee server 3. The application form 200 includes an application item entry field 201 for filling in items necessary for application for verification, such as the name and contact information of the installer, and a photo attachment field 202 for attaching a photograph of the power meter to be tested. And a photo attachment field 203 for attaching a photo of the meter for power purchase. In addition, when the installer of the solar power generation system 11 does not have an e-mail address, a notice of expiration of the examination period is sent to the installer by a letter or the like.

  When the installer who has received the verification period expiration notice S1 from the electric power company applies to the electric power company for the verification of the electric power meter 14, the installer fills in the application item entry field 201 of the application form 200. In addition, photographs of the power sale measuring instrument 14 to be verified and the power purchase measuring instrument 15 installed side by side with the power selling measuring instrument 14 are pasted in the photo attachment column 202 and the photo attachment column 203, respectively. Thereafter, the installer operates the installer terminal 1 to send the application form 200 to the center server 2 of the electric power company and perform the application procedure S2.

The center server 2 that has received the application procedure S2 performs a test acceptance process for the power sale measuring instrument 14. That is, the center server 2 sends a meter information request S3 to the fee server 3 in order to request information on the power sale measuring instrument 14 owned by the installer described in the application item entry field 201 of the application form 200. . Upon receipt of the meter information request S3, the fee server 3 checks the “identification number” from the name and address of the installer, and the “model” and “model” of the electricity sales meter corresponding to “A0123” of the “identification number”. Data representing the “manufacturer name”, “manufacturing number” and the like is sent to the center server 2 as instrument information S4. When the center server 2 receives the instrument information S4, the center server 2 attaches the data such as “model”, “manufacturer name”, “manufacture number”, etc. of the instrument information S4 to the photo attachment field 202 of the application form 200. Check if the data match by checking the model, manufacturer name, serial number, etc. If the information does not match, the center server 2 is attached to the photo attachment field 203 because the installer may have mistaken the meter for power sale 14 and the meter for power purchase 15. The data is compared with the data indicated by the photograph of the power purchase meter 15.

  The matching of the meter information S4 is completed, and there is no problem because the power meter 14 attached to the photo attachment column 202 of the application form 200 matches the power meter to be verified in the verification period expiration notice S1. For example, the center server 2 sends to the installer terminal 1 an order response S5 indicating that the application for verification of the power sale measuring instrument 14 has been accepted. The order response S5 includes data such as the model, manufacturer name, and manufacturing number of the power sale measuring instrument 14.

Further, the center server 2 creates data for ordering the construction from the data such as the model of the measuring instrument, the manufacturer name, and the serial number indicated by the photograph attached to the photograph attachment column 202 of the application form 200, and FIG. As shown in FIG. 4, the replacement work order S11 is sent to the replacement work company server 4. When the replacement work company server 4 receives the replacement work order S11, the replacement work company server 4 searches the replacement measuring machine management data 41 for an alternative measuring instrument compatible with the power sale measuring instrument 14 represented by the replacement work order S11. In FIG. 6 (b), since the data of the alternative measuring instrument whose “identification number” is “D001” conforms to the specification specified from the model of the measuring instrument 14 for power sale represented by the replacement work order S11, the replacement work is performed. The company server 4 determines that the alternative measuring instrument whose “identification number” is “D001” and the measuring instrument for power sale represented by the replacement work order S11 are compatible, and the alternative whose “identification number” is “D001”. Select a measuring instrument. And although illustration is abbreviate | omitted, the replacement construction company server 4 changes the "presence / absence of stock" of the alternative measuring instrument management data 41 to "none", and further, "lending date", "lending destination", The “scheduled return date” is entered and the alternative measuring instrument management data 41 is updated. The “rental destination” may be “A0123” that is the identification number of the installer managed by the fee server 3. Further, when the compatible alternative measuring instrument does not hit, the replacement construction company server 4 is returned the earliest from the “return date” and is compatible with the power sale measuring instrument 14 to be verified. Search for an alternative weigher.

  Thereafter, the worker of the replacement construction company visits the home of the solar power generation system 11 and performs the replacement work in the following procedure. First, the operator collates the currently installed power sale measuring instrument 14 with the data such as the model, manufacturer name, and manufacturing number indicated by the replacement work order S11, and determines the power sale measuring instrument 14 to be replaced. Check and perform replacement work. At that time, the power sale meter 14 and the alternative meter are photographed. By taking this picture, an image supporting the data such as the model of the power sale measuring instrument 14 and the alternative measuring instrument, the manufacturer name, the serial number, and the current number of instructions can be obtained. Thus, the replacement work by the operator is completed, and the power sale measuring instrument 14 is taken over by the replacement construction company.

Thereafter, the replacement work company server 4 creates a replacement work completion report S12 based on the photograph taken at the time of taking over the power sale measuring instrument 14, and the replacement work company server 4 completes the replacement work. Report S12 is sent to the center server 2. The replacement work completion report S12 indicating that the replacement work has been completed includes alternative measuring instrument information.
Exchange date
Model, manufacturer name, serial number, number of removal instructions of meter 14 for power sale
Includes data on the type, manufacturer name, serial number, and number of installation instructions of the alternative measuring instrument.

  When the center server 2 receives the replacement work completion report S12, the center server 2 creates a substitute measuring instrument information report S13 based on the substitute measuring instrument information included in the replacement work completion report S12, and charges the substitute measuring instrument information report S13 as a charge. Send to server 3. Upon receiving the alternative measuring instrument information report S13, the fee server 3 updates the power sale measuring instrument data 32 and the alternative measuring instrument data 33 with the alternative measuring instrument information of the alternative measuring instrument information report S13.

  For example, if the date when the alternative measuring instrument is attached is September 12, 2005 and the number of instructions of the power selling measuring instrument 14 at that time is 0010, the charge server 3 will display the "current month" “0010” (10 kWh) and “current sale amount” calculated from “0001” (1 kWh) of “previous month” and “0010” (10 kWh) of “current month” Then, “0009” (9 kWh) is set, and “verification” is set to “under verification”, and the data of the power sale meter 14 is created. Then, as shown in FIG. 10, the fee server 3 copies the data of the power sale meter 14 to another alternative storage area 34, and displays “the previous month indication number”, “current month” of the power sale meter data 32. Reset the “Number of instructions” and “Amount of electricity sold this month”.

  When the number of instructions of the alternative measuring instrument attached on September 12, 2005 is 0100, the fee server 3 is the “identification number” of the installer as shown in FIG. For “A0123”, “Model”, “Manufacturer name”, “Manufacturing number”, “Mounting date”, “Mounting instruction number” of the alternative measuring instruments are set to “DE34”, “Y company”, “8906”, “ 050912 ”,“ 0100 ”(100 kWh), and the alternative measuring instrument data 33 is updated.

  The replacement work company server 4 of the replacement work company sends a replacement work completion report S12, and also places a verification order S14 for the electric power meter 14 to the verification application service company server 5 of the verification application service company. Then, the replacement construction company transports the power sale measuring instrument 14 to the certification application agency.

  When the certification application agency completes the verification of the electricity sales meter 14, the certification application agency server 5 replaces the certification completion notification S 15 indicating the certification completion of the electricity sales meter 14 and the examination fee. It is sent to the replacement construction company server 4. When the replacement construction company server 4 receives the verification end notice S15, the replacement construction company takes over the power-measuring meter 14 from the verification application agency.

  Thereafter, the worker of the replacement construction company visits the home of the solar power generation system 11 and performs the replacement work in the following procedure. First, the operator checks the power sale measuring instrument 14 by comparing the power sale measuring instrument 14 he brought with the previous replacement work order S11, and further displays the alternative measuring instrument and the previous alternative measuring instrument information. Check the alternative weigher. After confirming the two measuring instruments, the operator takes a picture of the alternative measuring instrument in order to obtain the number of instructions of the alternative measuring instrument, the serial number, and the like. Next, the operator removes the alternative measuring instrument and attaches the certified measuring instrument 14 for power sale. Finally, the operator takes a picture of the power sale meter 14 in order to obtain the number of instructions and the serial number of the power sale meter 14. Thus, the replacement work by the operator is completed, the certified power sale measuring instrument 14 is operated again, and the alternative measuring instrument is taken over by the replacement construction company.

When the replacement construction company finishes taking over the substitute measuring instrument, it changes the “presence / absence of inventory” of the alternative measuring instrument management data 41 of the replacement construction company server 4 to “present”, ”,“ Scheduled return date ”, and the alternative measuring instrument management data 41 is updated. Further, the replacement construction company creates an exchange completion report S16 based on the photograph of the power sale measuring instrument 14 and the alternative measuring instrument, and the replacement construction company server 4 sends the replacement completion report S16. Send to the center server 2. The exchange end report S16 is
Weighing instrument information
Including data on billing for examination fees (replacement work fee, examination fee), and meter information
Exchange end date
Model, manufacturer name, serial number, number of installation instructions
Includes data on the type, manufacturer name, serial number, and removal instruction number of the alternative measuring instrument.

  When the center server 2 receives the exchange end report S16, the center server 2 charges an examination agency fee included in the exchange end report S16. At this time, when the installer does not wish to include the examination agency fee in the bill for the electric power fee, the center server 2 creates the examination agency fee billing information based on the examination agency fee and sends it to the fee storage company server 6. Further, when the installer wishes to include the examination agency fee in the billing for the electric power fee, the center server 2 sends the examination agency fee billing information S17 created based on the examination agency fee request to the fee server 3.

  When the center server 2 receives the exchange end report S <b> 16, the center server 2 sends the measuring instrument information S <b> 18 as the previous measuring instrument information to the fee server 3.

  When the fee server 3 receives the verification agent fee billing information S17, the billing agent fee included in the verification agent fee billing information S17 is used when billing the customer for the power fee using the meter data 31 for power purchase. Claim.

  Further, when the fee server 3 receives the meter information S18, the fee server 3 updates the meter for selling power 32. For example, when the number of indications of the verified power sale meter 14 included in the meter information S18 is 0015, the charge server 3 displays the “previous month” of the power sale meter data 32 as shown in FIG. The index of “” is set to “0015”, the “verification” is set to “completed”, and the power sale meter data 32 is updated. In addition, when the fee server 3 receives the measuring instrument information S18, the fee server 3 updates the alternative measuring instrument data 33. For example, if the replacement end date included in the measuring instrument information of the replacement end report S16 received from the center server 2 is September 25, 2005, and the number of instructions of the alternative measuring instrument at that time is 0210, 3, the alternative measuring instrument data 33 shown in FIG. 5B is set to “050925” as the “removal date” of the alternative measuring instrument data 33 as shown in FIG. Set to “0210”. Furthermore, from “0100” (100 kWh) which is the “number of attachment instructions” of “attachment date” and “0210” (210 kWh) which is the “number of removal instructions” of “detachment date”, the “power sales amount” is set to “ “0110” (110 kWh), and the alternative measuring instrument data 33 is updated.

  Thereafter, when the meter reading for this month indicates that, for example, the number of instructions for the power sale meter 14 is 0025, the fee server 3 sets the “number of instructions for this month” of the power sale meter data 32 in FIG. FIG. 12 shows that “0025” (25 kWh) is set to “0010” (10 kWh) from “0015” of “the previous month” and “0025” of “this month”. Thus, the power sale meter data 32 is updated. At this time, since the next verification expiration date is October 2015, 10 years later, the fee server 3 sets the “validation expiration date” of the power sale meter data 32 to “1510”.

  The fee server 3 calculates the amount of power sold by the installer of the solar power generation system 11 as follows. That is, as shown in FIG. 13, the amount of power sold from the previous meter reading date (September 1) to the date (September 12) when the alternative meter is attached is stored in the alternative storage area 34 (FIG. 10). It is “0009” (9 kWh) of “the amount of electricity sold this month”. In addition, the power sale amount measured by the alternative measuring instrument between the date when the alternative measuring instrument was attached (September 12) and the date when the alternative measuring instrument was removed (September 25) is the alternative measuring instrument data 33 (Fig. 11 (b)) is “0110” (110 kWh) of “amount of electricity sold”. Furthermore, the amount of power sold measured by the power meter 14 that has been verified between the date when the alternative meter was removed (September 25) and the current meter reading date (October 1) is Is “0010” (10 kWh) of “amount of electricity sold this month” stored in the measuring instrument data 32 (FIG. 12). The fee server 3 sets the amount of electricity sold this month, which is a sum of these values, to 129 kWh, and performs a fee payment procedure for the installer of the solar power generation system 11.

  Thus, according to this embodiment, when the power sale measuring instrument 14 owned by the installer of the solar power generation system 11 receives the certification, the center server 2, the charge server 3, and the replacement construction company server 4 are linked. This allows the installer to use an alternative meter instead of the power meter 14. In addition, since the alternative measuring instrument provided by the replacement construction company has been verified, even if a reverse power flow caused by the solar power generation system 11 occurs, it does not violate the provisions of the Measurement Law. Further, by linking the power sale meter data 32 and the alternative meter data 33, even if the power sale meter 14 is being verified, the power sale meter 14 is not interrupted without stopping the power sale. 1 can obtain an accurate amount of electric power sales, and the electric power meter 14 can be smoothly verified. Furthermore, since the photographed data is used to check the power sale measuring instrument 14 and the alternative measuring instruments and the indication number of each measuring instrument, misidentification of the measuring instrument and the indication number can be prevented.
